Due to the measures in force in the Republic of Slovenia for limiting the coronavirus (COVID-19) epidemic, SURS is faced with difficulties in data collection, checking and processing.
In April 2020, we collected retail prices of non-food goods and services to a greater extent by phone and through the websites of providers. Higher quality of the indices was ensured by using scanner data.
Where prices could not be collected or services were not provided, data were compiled in accordance with Eurostat recommendations
, so in some subgroups the published indices are less reliable than usual. For products that are still available in the market, the missing prices were imputed by using the price changes of similar products or of the nearest higher aggregate. For products and services that are not transacted anymore, the missing prices were imputed with all reliable price indices. In some cases, where there are reasons to expect that the prices will be the same once the situation will revert back to normal, carry forward method was used. For series with seasonal patterns (flights, accommodation services, package holidays), imputation with monthly change of the previous year was used. Share of imputed prices represents 22.7% of total harmonised index of consumer prices and 18.3% of total consumer price index. A detailed overview of the subgroups where the indices are less reliable and what method was used can be found here
As we continue to obtain scanner data weekly, the indices for divisions 01 (Food and non-alcoholic beverages) and 02 (Alcoholic beverages and tobacco) were calculated in the same way and therefore are of the same quality as in the months before the epidemic.
